Sherman’s family was “profoundly disappointed” with the DA’s decision and planned to file a multimillion-dollar civil lawsuit against all responsible parties, attorney Chris Stewart said Monday afternoon. The Sherman family will also seek a federal investigation.

“There was nothing inadvertent about the conduct of the officers and EMT that night,” the Sherman family said in an e-mailed statement. “It’s clear the District Attorney determined to blow off video of the event and the facts. Instead, he preferred to smear a dead guy’s name and avoid doing his job representing the community.”

During a November 2015 excursion for a family wedding, 32, Sherman, had bouts of paranoia and was not able to sleep, his family told investigators. His family supposed he’d taken drugs which caused his conduct.

If he could be taken into detention, based on the DA’s office at the Atlanta airport, Sherman’s family requested officers, but officers had no reason. Rather than making the flight home from Atlanta to Florida, the family rented a car due to the behaviour of Sherman.

As the family drove south on I 85, Sherman had bitten his fiancée, according to investigators and attempted to jump out of the car and onto the interstate highway. A relative called 911 plead for help as his unpredictable behaviour continued.

“He will kill us all,” the caller told the 911 operator.

The rental car was parked by the family next to the highway median, where deputies arrived and tried to handcuff Sherman, video revealed. Sherman was combative, so deputies deployed Tasers to subdue him.

“I am dead. I am dead!” As he lay said Sherman, handcuffed, face down on the floorboard of the car. After being zapped with a Taser by the deputies he was being held down by the weight of an EMT.

“I said I stop. I stop!” Sherman said.

Within minutes, Sherman was not responsive. He was pulled from the car, but couldn’t be revived. As they observed from several feet away, Mary Ann Sherman turned to her husband and said, “They Are killing him,” her husband after told the AJC.

An autopsy discovered Sherman died from a mix of variables, including the altercation, EMT and Tasers ’s compression on his torso, which raised his heart rate and raised his demand for oxygen, causing him to asphyxiate. Drugs weren’t found, according to researchers.

The Sherman family intends to discuss to the media Wednesday in Atlanta, Stewart said.
